https://elenajs.com/ --- Top Comments --- [akst]: I think it's better to think of "Web components" as "Custom Elements" they really aren't components in the way you think of components in other frameworks (which on the web introduced them first), and I think most of the dissatisfaction with them comes from trying pretend they're an alternative as they just aren't. Components in almost every other framework are efficient (efficient rendering runtime) and expressive (the ability not to have a root elemen... [hyperhello]: One fun thing I did once is use the custom elements API to make a custom tag <element-template>. When the page sees <element-template tag=what-name></element-template>, it looks inside, finds any <template></template> <script></script> and <style></style> tags, and builds a new custom element with that tag name and all the powers. Cool but not incredibly simple. Another amazing trick is to put a mutation observer on the... [thex10]: This article I came across last month on “Framework-agnostic design systems” happens to use this Elena library and I think explains its use case well: https://piccalil.li/blog/framework-agnostic-design-systems-p... [000ooo000]: Anyone doing anything interesting to use CSS libs like Bulma, Bootstrap with web components? Definitely feels like swimming against the tide. Got a hobby project in Lit.js, can't easily wrap (e.g.) `.btn` in a component without breaking styles because the component root/host ends up between `.btn-group` and `.btn`. One can manually add classes to the root/host but that only gets you so far. Ideally I could select when to render a root and I vaguely remember that Lit allows this... [socketcluster]: Web Components are great for doing multi-pass rendering with template placeholder substitution happening at multiple levels in the component hierarchy. The entire element HTML hierarchy can be declared in one place. It's extremely versatile. React cannot do this. It's difficult to explain without writing a whole essay but the benefits are very clear once you try this approach. </details>
